Google today announce three great new Nexus devices, all run Android 4.2, a new flavor of Jelly Bean. The three Nexus devices comes in 4.7" Nexus 4 smartphone by LG, Nexus 7 and Nexus 10 tablets. Here's more info from today's Google announcement:

Nexus 4 with Google Now and Photo Sphere

Nexus 4 is our latest smartphone, developed together with LG. It has a quad-core processor which means it's super fast, a crisp 4.7" (320 ppi) display that's perfect for looking at photos and watching YouTube, and with wireless charging you just set the phone down on a charging surface to power it up, no wires needed. While Nexus 4 is incredibly powerful under the hood, it also features the latest version of Jelly Bean, Android 4.2--the simplest and smartest version of Android yet. Starting with the camera, we've reinvented the photo experience with Photo Sphere, which lets you capture images that are literally larger than life. Snap shots up, down and in every direction to create stunning 360-degree immersive experiences that you can share on Google+ with friends and family--or you can add your Photo Sphere to Google Maps for the world to see.

Android 4.2 brings other great goodies like Gesture Typing, which lets you glide your finger over the letters you want to type on the keyboard--it makes typing fast, fun and a whole lot simpler. Android 4.2 also adds support for Miracast wireless displays so you can watch movies, YouTube videos, and play games right on your HDTV wirelessly.

Nexus 7: Thin, light and now even more portableNexus 7 brings you the best of Google-YouTube, Chrome, Gmail, Maps-and all the great content from Google Play in a slim, portable package that fits perfectly in your hand. To give you more room for all that great content you can now get Nexus 7 with 16GB ($199) or 32GB ($249) of storage. But we also wanted to make this highly portable tablet even more mobile. So we added HSPA+ mobile data. Nexus 7 is now also available with 32GB and HSPA+ mobile ($299), which can operate on more than 200 GSM providers worldwide, including AT&T in the US.

Nexus 10: Powerful and shareable Nexus 10 is the ultimate tablet for watching movies or reading magazines. We wanted to build a premium entertainment device, so we partnered with Samsung to do just that. Nexus 10 is the highest resolution tablet on the planet at 2560-by-1600 (300ppi), that's over 4 million pixels right in your hands. It comes with a powerful battery that will get you up to nine hours of video playback and more than 500 hours of standby time. With a set of front-facing stereo speakers, you can watch movies right from your Nexus 10 and they simply sound awesome. But what makes Nexus 10 unique is that it's the first truly shareable tablet. With Android 4.2, you can add multiple users and switch between them instantly right from the lockscreen. We believe that everyone should have quick and easy access to their own stuff -- email, apps, bookmarks, and more. That way, everyone can have their own home screens, their own music, and even their own high scores.
